Biomass consumption and smoke production by prehistoric and modern forest fires in western Washington

Wild and prescribed fires currently burn about 20,100 ha per year in Washington west of the Cascade Crest: prehistoric wildfires burned an estimated 19,200 ha per year. Modern burning consumes 38 g/m²/yr of fuel; the estimated prehistoric rate was 35 g/m²/yr over a 50-percent…

Characteristics of forest fuels, fires and emissions

Forest fires can be divided into two broad classes-wildfires and prescribed fires. Wildfires, whether caused by nature (lightning, etc.) or by the accidental or malicious acts of man, are not planned by forest managers and do not occur under controlled conditions. They can be…
